Machine tap set HSSE-Co 5 VAP in plastic case 7-pieces

Machine tap made from cobalt-alloyed and vaporized high-performance high-speed steel. For through-hole and blind-hole threads, in unalloyed and alloyed steels up to 1000 N/mm² strength, VA metals. The thread is cut in a single operation.

"Vaporizing” refers to the evaporation of a non-metallic oxide layer. Vaporizing acts as a separating layer and reduces the occurrence of cold welds. Cold welds are workpiece chips that weld onto the flank of the tap and damage the manufactured thread. The consequences of cold welding are torn and unclean thread flanks. VAP improves the adhesion of lubricants to the tool surface.
